4 Claims. (01. 200-39) This invention relates to time switches for opening and closing the circuits at a predetermined time of radio receiving sets, electric signs,

electric heating devices, etc. etc. One of the objects of the invention is to pro vide a clock with apair of alarm releases; one to close the circuit and the other to open same at predetermined times.

Another object of the invention is to provide" means whereby the alarm releaselevers or other means employed for operating the clock circuit making and breaking switch is held out of eflective relation with thesaid switch in order to permit the circuit breaking operating lever to function immediately after the circuit has been closed,

if so desired. e

, Still another object'of the invention is to provide an exterior switch which may be closed at will so that the clock may be detached or removed from the circuit and used with another device.

Another object is to produce 'a device of the character described in which the maximum sim-' plicity of construction and operation is secured. Other objects and advantages will appear as the nature of the improvements is better understood, the invention consisting substantiallyin the novel arrangement and co-relation of parts herein fully described, and illustrated in the accompanying drawings, wherein-similar reference characters are used to describe corresponding parts throughout the several views, and then finally pointed out and specifically defined and.

indicated in the appended claims. a

The disclosure made the basis of exemplif the present inventive concept suggests a practical embodiment thereof, but the invention is not to be restricted to the exact details of this dis-" closure, and the latter, therefore, is to be understood from an illustrative, rather than a restrictive standpoint.

The inventive idea involved is capable of re-' ceiving a variety of mechanical expressions. oneof which, for the purpose of illustration, is shown in the accompanying drawings in which Figure 2 is a front view of the clock mechanism with the dial removed. Figure 3 is a top plan view thereof.

Figure 4 is a side elevation thereof partly in Figure 1 is a fragmental front viewinelcva tion of a radio receiving set showing our im-E proved timing switch or clock connected thereto.

Figure '7 is a diagrammatic view showing the electric circuit.

Referring nowto the drawings in detail 10 indicates the clock mechanism of an ordinary alarm clock, which includes the usual spring operated gear wheel 11 which imparts rotary movement to a shaft 12 which carries the minute hand 13. A gear 14 in mesh with a pinion 15011. the shaft.v 12, carries a pinion 16 which is in mesh with a gear 1'7 having a sleeve 18 to which the hourhand 19'is secured. The pinion 16 is also in mesh with a second gear 20 which forms a part of the releasing means of the usual alarm mechanism' of the clock, and is rotatably mounted on a shaft'21. The shaft21 has mounted thereon a-hand 25 to the rear of which there is secured to the shaft 21 a disk 26 provided with a projection 27 riding on the end surface of a sleeve 28 gear 20 is rotatably mounted on a shaft 31 which is provided with a hand or pointer 32. I "The gear 30 is driven by meansof a pinion 33 secured. to a .gear 34in mesh with the pinion 15. Like the gear'20 the gear 30 is held against a spring arm 35 by means of a projection 36 riding on the end :surface' of a hub or sleeve 37 on the said gear 30. Both of the'spring' arms 29 and 35 are secured to the front plate 38 of theclock mechanism casing asat 39 and 40 respectively.

Our invention is shown as applied to radio receiving sets 45, but it may be just as readily applied to many other electrically operated devices. It for instance it is desired that the-radio play for aduration of two'hours, say between the hours of 7 and 9, the hand 25 is set at '7"(see Fig. 1) and the hand 32 is set at 9. When the hands 13 and 19 point to seven oclock, the edge 50 of the cam cut out 51 will be free of the projection 2'7 permitting the spring arm 29 to move thegear outwardly and straighten itself out to v 60 by means of lead wires 61 and 62. Insulating blocks 63 insulate the said pins from the rear plate 64 of the clock casing. The terminals 57 and 58 are carried by an insulation block 65 in the front plate 38.

' The free end '70 of the lever 29 carries a roller 71 whichwhen the said lever 29'snaps forwardly, rideson the under surfaceof aninclined plane .72 as the horizontal center line of the said roller is-below the top rear edge of the said inclined lane thus forcing the endof the-lever' with its projection 52'downwardly and holding the projection in the pathof the segment 53 until the forward movement of the said lever is completed.

The roller 71 thenrolls lands; on top of the for ward end of the inclined plane thus the ledge or projection '52 is high'enough to'be out of the path of segment 53. Shouldthe lower spring lever 35 be actuated to break the circuit before the upper lever has been again pushed rearwardly by the action of the cam 51 on the sleeve 28 but while it is moving rearwardly', projection 52 will be held out of the path of the segment '53 by riding on the upper surface of the inclined plane until at the end of rearward movemenhtheproiection again vmoves down to its originalpos'iticn ready to again engage the segmenLEThe construction and action of the .lowerflever. 35; is. exactly the same as that-of the lever just de- I scribed and the roller 71a carried. thereby vrides forwardly on the top surface of aniinclined plane 72a and returns on the 'undersurface thereof as indicated in Figure 6, the actuation of the said lever being accomplished by a cam and' a projection carrying disk exactly the same as the disk and cam 26 and 51 above described.

In order that the clock 10 may be disconnect-j,

ed from any device which it is operating or controlling, we provide a plug for engaging the terminal pins 59 and 60', which plug is provided with a switch 81- (see Fig. 7) which may close the circuit and short circuit the line before reaching the terminals 57 and 58, thus permitting the current to flow from its source 82 through a lead line 83 thence through the switch to which it is connected and thence through a terminal 84 lead wire 85 to the radio or other device and.

Having described our invention what we claim as newand desire to secure, by Letters Patent is:

1. In combination with an alarm clock, having a pair of slidable alarm release gears, a spring lever controlled by each of the said gears, a pair of electric terminals in electric circuit, a pivotally mounted arm, a contact pin thereon, a projection on each of the said levers for engagement with the said arm to rotate same about its pivot to engage or disengage the terminals when the gears are slid to release the spring. a roller on each of the said levers, and a plane so arranged with respect to the rollers as to-lift the lever projections out of the path of the arm after the said arm has beenso rotated.

*2. In combination with an alarm clock having an upper and lower slidable alarm releasing .gear, a spring lever controlled by each of the said gears, a pair of electric terminals in electric circuit, a pivotally mounted spring pressed segmerit, a metallic contact arm carried bythe said segment, a projection on each of the said levers for alternate engagement with the said segment to swing same about its pivot to close and open the circuit when their respective gears are slid forwardly, a roller on each of the levers, and a plane I so arranged with respect to the, rollers as to lift the respective lever projections out of the path of the arm after the said lever has been released by the gear.
